T 0 all whom it may concern.'

Be it known that l, MARTN Nnwoorrnaha citizen of the United States, andresiding in the city of Perth Amboy, county of Middle sex, in the Stateof New Jersey, have 1nvented certain new and useful Improvements inMachines for Punching Music- Sheets, of which the following is aspecification, reference being had to the accompanying drawing, forminga part hereof.

The machine which forms the subject of the present invention has beendesigned with special reference to its use in punching the marginal orside perforations 1n a musicsheet for the control, through suitabledevices in the player piano, of expression, and particularly for thepunching of perforations of this character which are not spacedregularly, either in longitudinal or lateral distribution. The mechanismin which the invention is embodied is applicable for other specialpurposes, and moreover, While reference is made herein to the punchingof sheets in the sense of forming perforations therein, it will beobvious that the mechanism is equally applicable to the marking ofsheets, by a punch or other suitable marker without actual perforation.It will be understood that the operation of the machine is controlled bya previously punched master sheet and is designed to effectautomatically the punching or marking of one or more sheets in exactaccordance with the previous punching of the master sheet. The machinewill be more fully explained hereinafter with reference to theaccompanying drawing iii-which it is illustrated and in which,-

Figure l is a plan View, partly broken out.

Fig. 10 is a detail view in perspective of a portion of the tracker-bar.

Fig. l1 is a detail view of the pneumatic shown in Fig. 3, inlongitudinal section through the valve g3.

In order that the relations of the parts may be the more readilyunderstood, it may be stated at the` beginning that the master sheet andthe sheet or sheets to be perforated or marked are-drawn forward inparallel relation, the one over a tracker-bar with pneumatic connectionsand the other over a dummy tracker-bar or supporting bar under thepunch, until a perforation in themaster sheet, which is to be reproducedin the other sheets, comes into registration with a slot or port in itstracker-bar. Thereupon movement of both sheets is stopped. The punch isthen shifted transversely until it reaches the same relative positionwith respect to the blank or sheet to the master sheet. rIhen the pun 'his operated and the movement of the Vsheets is recommenced and continueduntil another perforation in the master sheet comes into registrationwith the port or slot of its tracker-bar.

The feed-roll a for the perforated master sheet and the feed-roll a forthe sheet or sheets to be perforated, are preferably mounted side byside upon a common aXis and upon a common shaft a2. A brake a3 may beapplied to one of the rolls, such as the master roll, to preventoverrunning of either roll. The take-up roll at for the master sheet,and the take-up roll a5 for the sheet or sheets to be perforated, arealso mounted preferably on a common aXis and on a common sectional shafta6 and al, the two sections being united by a coupling as which permitsrelative angular adjustment of the two take-up rolls when necessary. Theshafts e2 and a, al are mounted in suitable bearings a9. The shaft a isdriven tl rough a friction clutch al@ from an alined and longitudinallymovable vshaft au which is actedupon by a spring Z12 to keep the membersof the friction clutch L10 normally in contact and may be driven fromany suitable source of power through a belt pulley m13'.

Z9 is a pneumatic block or casing, which comprises two independentpneumatic devices c and OZ which are connected, through a common windwayb and a common connection b2, with the source of suction of a vacuumcreating device, which is not shown and may be of any suitablecharacter. Each of the pneumatic devices c and Z may act, through itsarm c or Z, as the case may be, upon a clutch or collar Z143 on theshaft 11, to open the clutch x10 and therefore stop the movement of theshaft a, L7 and the master sheet and blank sheet or sheets. The

. pneumatic devices also perform other functions, as will be described.

As the two pneumatic devices or sets of devices c and Z are preciselythe same in construction7 a description of one, as Z, will suiiice forboth, but before proceeding with the description it may be stated thatthe tracker-bar e has formed therein a slot or port e, the ends of whichare connected re-` spectively by tubes e2 and c3, with the two pneumaticdevices or sets of devices c and eZ,

while the two portions of the slot e 'are y block or partition c4 areshifted as hereinafter described. The chamber Z2 of the pneumatic Z isseparated by a diaphragm Z6 from the chamber Z7 which is connected withthe windway b and, through a bleed hole Z8, with the chamber @Z2 or itsconnecting pipe c3. The chamber Z7 is also connected, through a port dg,with the chamber Z1, which is connected, through a port 0Z11, with thebellows Z12 of the pneumatic Z. The port Z9 is normally closed by avalve Z1'`, the stem of which rests upon the diaphragm Z6, the valve Z1?being provided with a bleed hole dx. The chamber 0Z10'also communicatesthrough a port Z14 with the chamber 5515, which communicates with theatmosphere. A diaphragm Z16 separates the chamber Z15 from a chamber Z17which communicates through a passage 0Z18, with the correspondingchamber 017 of the pneumatic 0,' and a 1` -tube Z19 with a pneumaticdevice q to be described, the chambers Z17 and @17.being connected incommon through the passage Z18 Yand the tube Z19, with the pneumaticdevice i g. The movable member of thefbellows .Z12 carries a striker Z20which, when the bellows is collapsed, acts upon the stem of the valve Z4to open the valve and place the chamber Y and channel Z2 incommunication with the of the pneumatic d, already described, its` lowerchamber being connected through the tube c2 with the right hand end ofthe slot c in the tracker e and, through a valve indicated by dottedlines at c1 in Fig. l, and a tube 05, with another part of the pneumaticdevice f.

The pneumatic device f, as previously stated, accomplishes the lateralshifting of the punch and at the same time the lateral shifting of themovable block e1, in one direction or the other, until it blanks theperforations of the master sheet, which may then be in registration withthe slot c of the tracker c. It comprises a bellows f,fthe movablemember of which has an arm f1. The latter is connected by a link f3 withthe slide 7L which carries the punch and, through an adjustable link e5,with the movable block e4. The tube d5, from the pneumatic device Z, isconnected to the lower chamber f3 on one side of the pneumatic device f,the said chamber being separated by a diaphragm f4 from a chamber f5which communicates with the main windway through a tube f6. The chamberf5 is common to both sides of the pneumatic. At one side, the chamber f5communicates through a port f7 with an upper chamber f8, whichcommunicates with the atmosphere through a port fg. The ports f7 and fgare controlled by a valve f1 which may be lifted by the diaphragm f1.The chamber 8 also communicates through a port f11 wit the bellowsmembers f', the port f11 beingclosed normally by a springpressed valve7112 which opens away from the bellows. The tube c5, from the pneumatico, communicates with a chamber f13 on the other side of the pneumatic,which chamber 7113 is separated by adiaphragm fm from the common chamberf5. The latter also communicates through a port f15 with a chamber 716on the side of the pneumatic corresponding to the tube c5. rlhe chamber)C16 also communicates through a port f17 with the atmosphere. A doublevalve f1.8, flf, which may be lifted by the diaphragm fm, controls theports V7"15 and f1?. The chamber f1@ also Vcommunicates with the bellowsf through a port f2 which is controlled by'a flap valve )C21 openingtoward the bellows.

When air at atmospheric pressure is admitted through the right handportion of the slot e of the trackerc, the tube c2, the valve c4 and thetube c5 to the corresponding chami-io ber flthe double valve f1'8,f19will .be lifted, shutting off communication between the chamber flsandthe-suction chamber f5 and placing it in communication with theatmosphere, whereby; air 'will be admitted through the flap valve f tothe bellows f and the latter will be permitted to expand. Through thearm f2, the `punch slide 7L and the block c4 will then krbe drawn to theright until the perforation of the -master sheetwhich initiated thisoperation is'blan-ked by the movable block. The punch carrier willthenbe stopped with its punch in a-.position which corresponds exactlyto that of the perforation in the master sheet which initiated theoperation. On the other hand, if air is admitted through a perforationin the master sheet to the left hand portion of the slot e, that is, tothe 4portion which lies to the left of the movable block e4, in whateverposition it may be, air at atmospheric pressure will then be admittedthrough the tube c3, the chamber' d2, the valve Z4 and the tube d5, tothe chamber f3. The diaphragm f4L will then lift the valve flo to placethe chamber. f8 in communication with the suction chamber f5 and cut oifcommunication between the same and the atmosphere through the port fg.As the valve fm opens vfrom the bellows, communication will then beestablished between the bellows f and the suction .chamber f5, andthrough the arm f2 and the described connections, the punch carrier hand they movableblock e4 will be moved tothe left until the latterblanks the perforation ofthe master sheet which initiated thisparticular movement.

The punch carrier 7L supports va vertically movable punch L, heldnormally in its `elevated position by a light spring 7b2. It isactuatedtovpunchor mark the paper tobe perforated or marked'by a hammerk3 with a head suiiciently broad to accommodate Athe limited lateralmovement of the punch, the hammer being pivoted on a suitablestandard h4and provided at its rear .end with a springpressed, pivoted toe h5,lhich permits lfree movement of the/hammer actuator in an upwarddirection, while providing anoperative engagement, when the head of thehammeris to be'lifted, by the downward movement of the actuator.

vThe hammer is actuated Vby an arm g which projects from themovablemember of a bellows g2 which forms part of the pneumatic deviceg, previously referred to. lThis device not only trips o-r actuatesthehammer, but it restarts the forward movement of the winding-on ortake-up rolls which were stopped during the punching operation, throughthe openings of the clutch am by the pneumatic devices c or d. Thebellows g2 is collapsed, under the control of an ordinary valve action,sufficiently indicated at g3, from the main windway through a tube g3,being extended by a spring action as usual. The

operation ofthe `valve g3, by which the bellows g2 is pl-acedincommunication with the tube v93X, is determined by a chamied g4controlled by a valve g5 which is carried by a pivoted arm gG. A-smallbellows 97 serves to operatethe -lever gcat the proper time, to lift thevalve g5, by means of a projecting lip g8 which engages a long, iiatspring g9 securedat its right hand end near the pivot of the lever g, tothe upper surface thereof, so that while the'lip g8 actuates the leverin its downward movement, it is permitted in its upward movement to passby the end of the spring gg, through the upward yielding of the latter.The bellows 97, extended by the spring glo, is collapsed by suction intwo tubes g11 and gif", which are connected respectively to the Atwoends of the slots c in the tracker bar e, which (when .covered by themaster sheet) is under suction through tubes c2 and e3 and thecorresponding bleed holes, one of which is shown at Z8 in Fig. 6,fromthe chamber 6V. rlhe bellows Q7 carries an arm 913 with a valve g14which vcontrols a channel Q15. The latter communicates, 'through thetube d previously referred to, withthe chamber G17 of the pneumatic cand, through the channel el, with the chamber d ofthe pneumatic d, sothat air is admitted to the chambers c17 and duwhenthe bellows g? isextended. A bleed hole g1G establishes communication between the channelg15 and the main windway through the tube g3".

lt will be understood that when a perforation in a master sheet passesover either end portion of the slot c of the tracker-bar e air iskadmitted through the tube c2 or the tube c3 under the correspondingdiaphragm ZG and the valve (Z13 is thereby lifted to close the port ZMand open the port dg, thereby placing the pneumatic c 12 in connectionwith the exhaust, whereby, through the arm (Z, the clutch al is openedand the movement of the master sheet and other parts is stopped. rl`henthe valve-block c4 is moved, together with the punch, until it blanksthe perforation in the master sheet. VThis blanking of the perforationin the master sheet would result in a restarting Aof the master sheetbefore the operation'of the punch if it were not that devices areprovided for the purpose of preventing such restarting by preventingconnection of the pneumatic el with the atmosphere and the consequentexpansion of the pneumatic and closing of the clutch.

Connection of the pneumatic (X12 with the atmosphere at d is preventedby closing the port ZM by the valve c l which is carried by thediaphragm dm. The chamber d above the diaphragm Zw is connected, asalready described, through the tube dlg, with the channel g previouslyyreferred to, so that when the channel 915 is opened by the lifting ofthe valve g, by the expansion of the small bellows 97, air atatmospheric pressure is admitted above the diaphragm d and the valve 2carried 'thereby' then drops upon the port c 14 and closes it. The bleedhole el* in the valve Z13 is provided in order that the valve 21carried'by the diaphragm @Z716 may be held more closely to its seat bythe suction through the bleed hole ZX in the valve Z13 so long as thevalve Z1? is held up against the port d by the diaphragm dw.

At the same time that air is admitted through the perforation in themaster sheet and through one end portion or the other of the slote inthe tracker e, air at atmospheric pressure is also admitted through thetube g11 or the tube 912, as the case may be, to the small bellows g7,which is thereupon eX- panded by its spring so as to lift the valve 911from its seat and admit air to the channel 915 as already described.

When the perforation in the master sheet is blanked by the movablevalve-block e1, air at atmospheric pressure is cut off from the bellowsg7 as well as from the chamber below the diaphragm CZG, and the bellowsg7 will then be collapsed through the tubes 911, g1g, the slot e', thetubes e2, .e3 and the bleed holes d8.

' tion through the tube d1, the bleed hole Q16 Cil and the tube g3,whereby the diaphragm Zw is lifted and its valve l2? is carried awayfrom the port al, so that air at atmospheric pressure is then admittedto the pneumatic du which immediately expands and closes the clutch.This action restarts the movement of the master sheet, but not until thehammer has been operated to actuate the punch.

The operation of the machine as a whole has now been suliicientlydescribed and need not be further explained herein.

It will be understood that the essential features of the machine may beembodied in arrangements and combinations other than as Vshown anddescribed herein and that the invention, except as pointed out in theclaims, is not limited tothe particular construction, arrangement andcombination of parts in which it has been illustrated and describedherein as embodied.
